Answer:
C. (7, 14)
Step-by-step explanation:
You are given the equation and points (x, y) to plug into that equation. See which ones satisfy. The left side must equal the right side (7 in this case) when evaluating...
-5(7) + 3(14) = 7
-35 + 42 = 7
7 = 7
The point (7, 14) works. The other points will not yield the same result..
EX: (2, -1)
B is a wrong answer because...
-5(2) + 3(-1) = 7
-10 - 3 = 7
-13 = 7
-13 does not equal 7, so that is a wrong answer
Answer: $12.75 for the popcorn and $48.00 for the drinks.
Step-by-step explanation:
Answer:
13, 0.325, and -142
Step-by-step explanation:
13 because the number terminates, 0.325 because the decimal terminates, and -142 because it is a negative integer, the rule with rational numbers is that they must follow a pattern if continuing or terminate or be a positive or negative integer. For example, pi is an irrational number so is 0.45623... and 50--√.
Answer:
72
Step-by-step explanation:
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.
-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.
-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.
-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.
-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.
So, the table/coordinates are:
(-2, 5)
(0, 2)
(2, -1)
(4, -4)
I hope this makes the process clear.
